[2] The team achieved success for the first time when it earned promotion to the then tier-one Südkreisliga in 1922 after a title in the local Northern Harz championship.

GSC was grouped in the Kreisliga Südkreis-Group 1, a league made up of eight teams and won by SV Arminia Hannover that season, with Goslar coming seventh.

In post-Second World War Germany, the club, playing under the name of TSV Goslar, gained entry to the tier-two Landesliga Niedersachsen-Braunschweig in 1947.

When the league, now renamed Verbandsliga Niedersachsen, was split into two regional divisions again in 1994, Goslar gained entry to the eastern one, where it finished tenth in its first year.

[15] The team spent its following seasons as a mid-table side again, but came close to promotion in 1999–2000, when it finished third, three points behind the league champion.

[17] The following year, the team finished twelfth in the league and was relegated by one point, back to the tier-six Bezirksoberliga Braunschweig.

[21] With only the winner of this two games gaining promotion, GSC lost to VfB at home 1–0 but then won in Oldenburg 2–1 and earned the right to play in the Regionalliga Nord in 2009–10 on the Away goals rule.

In 2010-11 the club came only seventh but won the league championship the year after and earned another promotion to the Regionalliga and spend the next four seasons at this level.

Finishing 16th in 2015–16 and being relegated the club declined to apply for an Oberliga licence and instead dropped down to the tier six Landesliga Braunschweig.
